          <p>Explore graph analytics.
          Extract and summarize information about the documents and terms in an Elasticsearch data stream or index.
          The easiest way to understand the behavior of this API is to use the Graph UI to explore connections.
          An initial request to the <code>_explore</code> API contains a seed query that identifies the documents of interest and specifies the fields that define the vertices and connections you want to include in the graph.
          Subsequent requests enable you to spider out from one more vertices of interest.
          You can exclude vertices that have already been returned.</p>

        :param index: Name of the index.
        :param connections: Specifies or more fields from which you want to extract terms
            that are associated with the specified vertices.
        :param controls: Direct the Graph API how to build the graph.
        :param query: A seed query that identifies the documents of interest. Can be
            any valid Elasticsearch query.
        :param routing: Custom value used to route operations to a specific shard.
        :param timeout: Specifies the period of time to wait for a response from each
            shard. If no response is received before the timeout expires, the request
            fails and returns an error. Defaults to no timeout.
        :param vertices: Specifies one or more fields that contain the terms you want
            to include in the graph as vertices.
